BATTERY TERMINAL Filed Oct. 28, 1933 M mfovheki Patented July 30, 1935UNITED STATES PATENT OFFICE BATTERY TERMINAL George Koops, Holland,Mich. Application October 28, 1933, Serial No. 695,608

1 Claim. (01. 173-259) This invention relates to a battery terminal. Oneof the primary advantages of my device resides in its outwardly extendedslotted ears whereby the bolt means, which clamps it in place, may bequickly and easily removed from its more or less corroded seat by asimple prying operation and thus much time is saved as well as annoyanceavoided.

Another feature of my invention resides in the diverging outer surfacesof the ears whereby tightening of the bolt causes it to slide inwardlyand prevents any accidental releasing movement from occurring.

Yet another advantage resides in the provision of lug means forpreventing rotation of the head of the bolt.

Other advantages will become apparent as the description proceeds. Inthe drawing:-

0 Fig. 1 is a plan view of my battery terminal as applied to the post ofthe ordinary storage battery.

Fig. 2 is a side view of the battery terminal with the clamping boltlocated therein.

Fig. 3 is a side View of Fig. 1, partly in section.

Fig. 4 is a plan view of my device with the clamping bolt removed.

Fig. 5 is a side view of Fig. 4.

Fig. 6 is a perspective view of the clamp.

Similar numerals refer to similar parts throughout the several views.

Referring particularly to Figs. 1 and 3, H1 indicates a storage batteryhaving the usual tapered post ll extending upwardly therefrom.

My device is formed of a body portion I2, such being of substantiallycylindrical shape, and being formed of brass or the like which may becoated with lead or electro-plated. It is to be understood that the bodyis formed of metal having more or less resiliency whereby it willnormally spring outwardly to such a size as to permit it to be readilyslid to its operative position over the battery post II.

A socket member I3 is integrally formed with the body portion l2 andreceives a conductor member l4 therein. See Figs. 1 and 2.

At the opposite side of the body ears l5 and I6 are formed, these earshaving slots l1 and I 8 respectively formed therein.

As clearly shown in Fig. 3, these slots are parallel to one another andextend angularly upward whereby a tool, indicated at H! in Fig. 3,

may be inserted adjacent the post ll so as to pry the fastening bolt '20out of the slots.

A projection 2|, see Figs. 4, 5 and 6, extends outwardly from the bottomportion of the ear l6 and contacts against the head of the bolt 20 5when the bolt 20 is located in the slots and prevents turning of thebolt. Thus the nut on the bolt may be tightened to cause the ears l5 andI6 to approach one another and to tightly clamp the post lltherebetween.

The outer surfaces 22 and 23 of the ears l5 and I6 extend outwardlyangularly with respect to one another and thus exert pressure on thehead of the bolt and the nut thereof, see Fig. l, to cause it toslide'inwardly towards the battery 16 post H and thus absolutely preventthe bolt from working out accidentally. This is a very important featureof my invention and it is to be noted that the ears l5 and iii areresilient and exert an outward pressure at all times and 20 after thebolt 20 has been removed, as by means of the tool l9 shown in Fig. 3,that these cars will spring apart, see Fig. 4, and thus the body! willbe readily insertable upon the battery post ll.

Having thus revealed this invention, I claim as new and desire to securethe following combinations and elements, or equivalents thereof, by

Letters Patent of the United States.

I claim:- 30

In combination with a battery post having a substantially cylindricalupper end, of a battery terminal having a body'extending partly aroundthe upper end of the post and terminating in a socket atone side and incars at the opposite side, 5 the ears being spaced apart sufficiently topermit the insertion of a screw driver therebetween, the outer faces ofsaid ears diverging outwardly from each other when the same are inoperative position as well as inoperative position, the ears also havingslots therein, the slots extend ing inwardly and downwardly andterminating 1 short of the post whereby a'screw driver may be insertedbetween the post and the closed ends of the slots, a bolt received insaid slots,a nut 45 engaged thereon, the head of the bolt engagingagainst the outer face of the other ear for the purpose described, and alug positioned on the outer face of one of said ears, said lug having asurface substantially parallel to the sides of 50 the adjacent slot.
